Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application is based on and claims the benefit of priority to Korean Patent Application No. 10-2022-0064203, filed on May 25, 2022, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.

TECHNICAL FIELD

The present disclosure relates to a mounting system for a heating, ventilation, and air conditioning (HVAC) component, and more particularly, to a mounting system for an HVAC component providing sufficient stiffness of a dash panel and sufficient mounting stiffness of an HVAC component mounted on the dash panel.

BACKGROUND

A vehicle includes a dash panel configured to divide a front compartment from a passenger compartment. A front surface of the dash panel faces the front compartment, and a rear surface of the dash panel faces the passenger compartment. A powertrain including a prime mover may be disposed in the front compartment. For example, in an internal combustion engine vehicle, a mechanical powertrain system including an internal combustion engine and a transmission may be disposed in the front compartment, and in an electric vehicle, an electric powertrain system including an electric motor, an inverter, and a transmission may be disposed in the front compartment.

Since the electric vehicle has no internal combustion engine in the front compartment, the front compartment of the electric vehicle may have a relatively larger space than the front compartment of the internal combustion engine vehicle. As a battery is disposed under a floor of the electric vehicle, the electric vehicle may have a flat floor structure.

Since the existing internal combustion engine vehicle has a heating, ventilation, and air conditioning (HVAC) module in the passenger compartment, the space of the passenger compartment may be relatively narrow. For example, as the HVAC module in the internal combustion engine vehicle is mounted on the rear surface of the dash panel, the HVAC module may be disposed in the passenger compartment.

On the other hand, as the front compartment of the electric vehicle does not have any internal combustion engine, it may provide enough space for receiving at least some HVAC components of the HVAC module. Accordingly, when at least some HVAC components of the HVAC module are received in the front compartment of the electric vehicle, the passenger compartment of the electric vehicle may provide a relatively large space. In particular, a cockpit located on the front of the passenger compartment may be slimmed down and a flat floor structure may be built more easily.

The above information described in this background section is provided to assist in understanding the background of the inventive concept, and may include any technical concept which is not considered as the prior art that is already known to those skilled in the art.

SUMMARY

The present disclosure has been made to solve the above-mentioned problems occurring in the prior art while advantages achieved by the prior art are maintained intact.

An aspect of the present disclosure provides a mounting system for a heating, ventilation, and air conditioning (HVAC) component designed to allow at least one HVAC component of an HVAC module to be firmly mounted on a front surface of a dash panel (i.e., the surface of the dash panel facing a front compartment) by increasing stiffness of the dash panel using a vertical reinforcing member, a horizontal bracket, and/or a horizontal reinforcing member, thereby locating at least one HVAC component of the HVAC module in the front compartment, which makes it possible to provide a relatively large space in a passenger compartment, to slim down a cockpit located on the front of the passenger compartment, and to easily build a flat floor structure of a vehicle body.

According to an aspect of the present disclosure, a mounting system for an HVAC component may include a dash panel configured to divide a front compartment from a passenger compartment, and having an opening, an HVAC component located in the front compartment, a plurality of mounting portions located around the opening, and configured to mount the HVAC component, and a vertical reinforcing member located adjacent to the opening, and extending along the height of the dash panel. The dash panel may include a first surface facing the front compartment, and a second surface facing the passenger compartment. At least some of the plurality of mounting portions may be provided to the vertical reinforcing member. The vertical reinforcing member may be mounted on the dash panel around the opening of the dash panel and extend along the height of the dash panel so that the vertical reinforcing member may increase stiffness of the dash panel.

The mounting system may further include a plurality of horizontal brackets located adjacent to the opening, and extending along the length of the dash panel. At least some of the plurality of mounting portions may be provided to the horizontal brackets. The plurality of horizontal brackets may be located adjacent to the opening so that the plurality of horizontal brackets may increase stiffness of the dash panel.

The vertical reinforcing member and the horizontal brackets may be mounted on the first surface of the dash panel, and the plurality of mounting portions may be provided to the vertical reinforcing member and the horizontal brackets. As the plurality of mounting portions are provided to the vertical reinforcing member and the horizontal brackets, and the vertical reinforcing member and the horizontal brackets are mounted on the first surface of the dash panel, the HVAC component may be firmly mounted on the first surface of the dash panel through the vertical reinforcing member and the horizontal brackets so that mounting stiffness of the HVAC component may be sufficiently achieved. In particular, as the HVAC component is mounted on the first surface of the dash panel, the HVAC component may be located in the front compartment, and thus a relatively large space may be provided in the passenger compartment.

The mounting system may further include a horizontal reinforcing member located adjacent to the opening, extending along the length of the dash panel, and connected to the vertical reinforcing member. As the horizontal reinforcing member extends along the length of the dash panel around the opening of the dash panel and is connected to the vertical reinforcing member, the stiffness of the dash panel may be improved.

The vertical reinforcing member and the horizontal reinforcing member may be mounted on the first surface of the dash panel, and the plurality of mounting portions may be provided to the vertical reinforcing member and the horizontal reinforcing member. As the plurality of mounting portions are provided to the vertical reinforcing member and the horizontal reinforcing member, and the vertical reinforcing member and the horizontal reinforcing member are mounted on the first surface of the dash panel, the HVAC component may be firmly mounted on the first surface of the dash panel through the vertical reinforcing member and the horizontal reinforcing member so that the mounting stiffness of the HVAC component may be sufficiently achieved.

The mounting system may further include a pair of rear lower members mounted on both side edges of the dash panel; and a dash cross member located adjacent to the opening, extending along the length of the dash panel, and connecting the pair of rear lower members. The dash cross member may have at least one mounting portion for mounting the HVAC component. As the dash cross member connecting the pair of rear lower members extends along the length of the dash panel around the opening of the dash panel, peripheral stiffness of the opening of the dash panel may be improved.

The mounting system may further include a stiffened cross member mounted on the second surface of the dash panel, and extending along the length of the dash panel. As the stiffened cross member extends along the length of the dash panel on the second surface of the dash panel, the stiffness of the dash panel may be further improved.

The mounting system may further include a pair of front pillars connected to both sides of the dash panel; and a pair of end brackets fixed to both ends of the stiffened cross member, and connected to the pair of front pillars, respectively. The stiffened cross member may firmly connect the pair of front pillars through the pair of end brackets. Thus, the stiffness of the dash panel may be further improved, and a load applied to the dash panel may be uniformly distributed and transferred to the pair of front pillars.

The stiffened cross member may be fixed to a top edge of the dash panel, and the stiffened cross member may be located adjacent to the opening. As the stiffened cross member is located adjacent to the opening of the dash panel, the stiffness of the dash panel may be improved.

The mounting system may further include a vertical stiffened member fixed to the second surface of the dash panel, and extending along the height of the dash panel. As the vertical stiffened member is mounted on the second surface of the dash panel, the stiffness of the dash panel may be further improved.

The vertical stiffened member may be located adjacent to the opening, and be connected to the stiffened cross member. As the vertical stiffened member is connected to the stiffened cross member around the opening, the stiffness of the dash panel may be improved.

The mounting system may further include a reinforcement plate mounted on the second surface of the dash panel, and having an opening aligned with the opening of the dash panel. The reinforcement plate may overlap a peripheral portion of the opening of the dash panel on the second surface of the dash panel. As the reinforcement plate is fixed to the peripheral portion of the opening of the dash panel, the stiffness of the dash panel may be further improved.

The mounting system may further include a pair of mounting brackets mounted on the first surface of the dash panel, and extending from a top edge of the dash panel toward the opening of the dash panel, and a horizontal reinforcing member located adjacent to the opening, extending along the length of the dash panel, and connecting the pair of mounting brackets. A bottom end of each mounting bracket may be adjacent to a top edge of the opening. As the pair of mounting brackets are located adjacent to the opening of the dash panel, and the horizontal reinforcing member connects the pair of mounting brackets, the stiffness of the dash panel may be improved.

The mounting system may further include a pair of damper housings disposed in front of the dash panel, and a pair of strut bars connecting the pair of damper housings and the pair of mounting brackets, respectively. As the pair of mounting brackets are connected to the pair of damper housings through the pair of strut bars, a load applied to the dash panel may be uniformly distributed and transferred to the pair of strut bars.

The mounting system may further include a cross bar connecting the pair of damper housings. The cross bar may have at least one mounting portion, and a front portion of the HVAC component may be mounted on the mounting portion of the cross bar. As the front portion of the HVAC component is mounted on the mounting portion of the cross bar, the HVAC component may be firmly supported between the first surface of the dash panel and the cross bar, and thus the mounting stiffness of the HVAC component located in the front compartment of the vehicle may be sufficiently achieved.

One of the pair of mounting brackets may be connected to the vertical reinforcing member, and the mounting bracket and the vertical reinforcing member may be continuously connected along the height of the dash panel. As the mounting bracket and the vertical reinforcing member are continuously connected along the height of the dash panel, the stiffness of the dash panel may be further improved.

The pair of mounting brackets may be fixed to a cowl, and the cowl may be disposed on the dash panel. As the pair of mounting brackets are connected to the cowl disposed on the dash panel, the dash panel may define various load paths by the pair of mounting brackets and the cowl.

Each mounting portion may include mounting hardware to which a mounting lug of the HVAC component is mounted, and a stiffened portion provided around the mounting hardware and supporting the mounting hardware. As the mounting portion has the stiffened portion provided around the mounting hardware and supporting the mounting hardware, the stiffened portion may increase the stiffness of the mounting portion and the support stiffness of the mounting hardware even when the dash panel, the reinforcing members, and the like are made of a material (e.g. an aluminum material) with lower stiffness than steel. Thus, the mounting stiffness of the HVAC components may be sufficiently achieved.
